Unique interface reactions at the surface of sea-salt particles have been suggested as an important source of photolyzable gas-phase halogen species in the troposphere. Many factors influence the relative importance of interface chemistry compared to aqueous-phase chemistry. The Model of Aerosol, Gas, and Interfacial Chemistry (MAGIC 2.0) is used to study the influence of interface reactions on...
Plant height has long been an important agronomic trait in maize breeding. Many plant height QTLs have been reported, but few of these have been cloned. In this study, a major plant height QTL, qph1, was mapped to a 1.6kb interval in Brachytic2 (Br2) coding sequence on maize chromosome 1. A naturally occurring rare SNP in qph1, which resulted in an amino acid substitution, was validated as the ...
The marine globin dehaloperoxidase-hemoglobin (DHP) from Amphitrite ornata was found to catalyze the H2O2-dependent oxidation of monohaloindoles, a previously unknown class of substrate for DHP. Using 5-Br-indole as a representative substrate, the major monooxygenated products were found to be 5-Br-2-oxindole and 5-Br-3-oxindolenine. Isotope labeling studies confirmed that the oxygen atom incor...
We present an elementary proof of an important result of Y. Brenier ([Br1], [Br2]), namely that vector fields in R satisfying a nondegeneracy condition admit the polar factorization (∗) u(x) = ∇ψ(s(x)), where ψ is a convex function and s is a measure-preserving mapping. Brenier solves a minimization problem using Monge-Kantorovich theory, whereas we turn our attention to a dual problem, whose E...
In order to manage watersheds, especially in mountainous areas that are not adequately station hydrological phenomena simulation is important. In this study, the SWAT model used to simulate hydrologic basin Eskandari. Calibration and validation of models for the periods 2006-1992 and 2009-2015, respectively, using the algorithm SUFI2 in software SWAT CUP was done. To evaluate the simulation re...
Aqueous rechargeable zinc batteries are very attractive for energy storage applications due to their low cost and high safety. However, operating voltages limit further development. For the first time, this work proposes a unique approach increase of aqueous by using tri-functional metallic bipolar electrode with good electrochemical activity ultrahigh electronic conductivity, which not only pa...
An ab initio study of the interactions between H2O and Cl2+ and H2O and Br2+ has been performed. We present calculations using both the UMP2 level and the UCCSD(T) level of correlation with the aug-cc-pVTZ basis. The aug-cc-pVQZ basis was tested for selected geometries and was found to yield results similar to the smaller basis. For the H2O-Cl2+ cation, a C2v structure has been identified as th...
Benzyl amine was coupled to the dangling carboxylic acid groups of the platinum(II) complex [Pt(edda)Cl2], where edda = ethylenediamine-N,N'-diacetic acid, to give the diamidetethered complex [Pt(L)Cl2] (1), where L = ethylenediamine-N,N'-bis(N-benzylacetamide). Complex 1 was oxidized with both PhICl2 and Br2. Oxidation with PhICl2 cleanly afforded the tetrachloride complex, [Pt(L)Cl4] (2), whe...
